I am testing an rc of ups-nut 2.8.5 (wip/ups-nut), and while it's mostly
ok, building on NetBSD 11 under pkgrsrc gets me:
make[2]: warning: Invalid internal option "-J" in "/tmp/work/wip/ups-nut/work/nut-2.8.4.1239/tools"; see the manual page
upstream doesn't think -J is in the sources.
If I build MAKE_JOBS=1 (instead of 4 which my mk.conf defaults to), I
don't get the error.
If I build -j4 in a subdir -- that provoked the warning from top level,
then I don't get a warning.
Building on 9 or 10 does not get this error.
Has anybody seen this?
